 单文件日志

import logging
  
  
logging.basicConfig(filename='log.log',
                    format='%(asctime)s - %(name)s - %(levelname)s -%(module)s:  %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S %p',
                    level=10)
  
logging.debug('debug')
logging.info('info')
logging.warning('warning')
logging.error('error')
logging.critical('critical')
logging.log(10,'log')

对于上述记录日志的功能，只能将日志记录在单文件中，如果想要设置多个日志文件，logging.basicConfig将无法完成，需要自定义文件和日志操作对象。

# 定义文件
file_1_1 = logging.FileHandler('l1_1.log', 'a', encoding='utf-8')
fmt = logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s:  %(message)s")
file_1_1.setFormatter(fmt)

file_1_2 = logging.FileHandler('l1_2.log', 'a', encoding='utf-8')
fmt = logging.Formatter()
file_1_2.setFormatter(fmt)

# 定义日志
logger1 = logging.Logger('s1', level=logging.ERROR)
logger1.addHandler(file_1_1)
logger1.addHandler(file_1_2)


# 写日志
logger1.critical('1111')

 

# 定义文件
file_2_1 = logging.FileHandler('l2_1.log', 'a')
fmt = logging.Formatter()
file_2_1.setFormatter(fmt)

# 定义日志
logger2 = logging.Logger('s2', level=logging.INFO)
logger2.addHandler(file_2_1)

　日志等级

CRITICAL = 50
FATAL = CRITICAL
ERROR = 40
WARNING = 30
WARN = WARNING
INFO = 20
DEBUG = 10
NOTSET = 0
